1 Making SDN a Reality Douglas Gourlay Vice President Arista Networks

2 What is SDN? Purist View a strict separation of control plane and data plane SDN = Openflow Pragmatic View a network architecture designed to be programmed by high-level languages and APIs SDN = Programmability A Common View SDN = Network Virtualization

3 Why SDN? Networks are an order of magnitude larger; automation has lagged SDN solves inflexibilities and inefficiencies that inhibit scale & automation Copyright All Rights Reserved.

4 SDN is More than Just OpenFlow Configuration Signaling Status/Alerts Statistics Sampling OpenFlow CLI NetConf/YANG XML-RPC RESTful APIs, XMPP vsphere APIs OpenStack NetFlow, sflow, jflow, IPFIX, NetStream SNMP + I2RS, ForCES, SDNP, PCE, NFV etc

5 What we are introducing today Arista s SDN View SDN is a software-to-infrastructure interface that allows applications to drive infrastructure actions, delivering capabilities like Network Virtualization and Orchestration.

6 Arista SDN Phases: Making SDN a Reality Ubiquitous Network-wide Phase Virtualization All devices virtual and SW provisioned Phase Open APIs Control & Data Orchestration Integration Rapid Service Delivery Phase Arista EOS Self Healing Event Driven Open Programmable Foundation

7 Recent and and near-term SDN innovations Integration of Arista EOS with Openstack - enables fully automated provisioning Contribution to Openstack that enables unified physical and virtual network provisioning Openflow support with new Direct Flow mode for controller-less operation Hybrid support of Openflow to enable flow provisioning on top of existing production networks Arista eapi Integration with several cloud and application partners

8 Arista EOS - programmable network O/S Partner Integration - F5, Palo Alto, Splunk, etc Packaged Extensions Routing Protocols Interface Manager CLI Spanning Tree ASIC Drivers LED XMPP Client vcenter API KVM - Virtual Machine - CloudVision, etc Openflow 1.0/1.3 - multi-vendor services Direct Flow Programming - customized flow pathing sysdb - Central State Database Stock x64 Linux Kernel EOS - Extensible Network O/S EOS eapi - JSON Web Services API Local Scripts - Python, TCL, Shell Local Daemons/Extensions - C++, Python, etc

9 Arista DirectFlow Control Enables direct CLI and eapi control over specific flow switching operations Extends the capabilities of OpenFlow with controller-less operation and enables per-flow pattern-matching with full control Arista eapi or CLI Enables firewall load balancing, purpose-built backup network consolidation, etc. Available Summer 2013

13 Summary Arista EOS offers customers the best option for trying and deploying SDN capabilities. Customers can freely choose controllers, direct flow capabilities, protocol driven topologies, or hybrid approaches. No barrier to entry, no barrier to exit. Arista EOS enables orchestration of the network with VMware and Openstack - full VM Tracer capabilities and auto-provisioning for 90%+ of the public and private cloud market! Competing solutions are largely proprietary, and are designed to force single-vendor or architectural lock-in. Simply the best networking for the cloud
